Display Testing and Quality Assurance Procedures

Display Testing and Quality Assurance Procedures

At CrateKart, we talk a lot about quality but what does that really mean?

We do a lot of testing, tracking, and tinkering to ensure we have the highest quality displays. And we back it up with 30 Days Money Back Guarantee & 1 Year Warranty.

Your time should be spent fixing, not wasted on a defective display.

Serialized Inventory

Every display we sell has a serialized inventory code that allows us to track every single detail about the display in our warehouse—where it was manufactured and by whom it was tested, stocked, and shipped.

If one lot has an exceptionally high “incident” rate, we can quickly troubleshoot the weakest link in our supply chain and identify what to do differently in the future. All of this data means that we’re constantly making smarter decisions about our manufacturing, testing practices, and shipping methods.

Checks Performed

  • No scratches or manufacturing flaws in the glass.
  • No separation between glass and plastic frame.
  • Cables and connectors inspected for damage.
  • Stable image with no flickering.
  • No excessive light leakage from the sides of the LCD.
  • Digitizer checked for proper functionality, including 3D touch.
  • Measured for satisfactory luminance and even distribution of backlight.
  • Inspected for distorted video, lines, and dead pixels.

    Color Analysis of Screens

    We test each screen that rolls through our building. First, we connect the LCDs to an iPhone test bench to quickly weed out the screens that have obvious display issues. Second, we ask a robot for a second opinion. Using a state-of-the-art color analyzer, we're able to identify defects indiscernible to the human eye. Does that screen look a little too pink? Is the backlight working well? Is it too dim? Those are all questions that we can answer with quantifiable analysis. There's no room for opinions on what counts as good enough—we only sell the best.

    Reject Rates

    Every display we sell is tested. Right here in our warehouse. We couldn't be more proud of our team of highly trained individuals that handle our quality control.

    Every batch our manufacturers ship is so thoroughly tested that it's not uncommon for us to reject 20% of a given batch. Dealing with problem parts at the source means you or your customer won't have to deal with the headache of a failed part.

    It would be a lot easier to just turn around and ship every display we receive. But we'll never do that—you're welcome.

    Low Return Rates

    Because of our in-house testing method, our return rate (from you, our customer) is very low. And we’re proud of that. We’re not really sure how any defective displays sneak through our testing process, to be honest. But alas, it happens. It just happens way less often than the other guys.


    Like we said, every now and then a defective display sneaks through our Quality Control team. When that happens, rest assured that the display is covered by 30 Days Money Back Guarantee & 1 Year Warranty that we’ll actually honor. All you have to do is ask.
